The tire on a bicycle is filled with air to a gauge pressure of 744 kpa at 20◦c. what is the gauge pressure in the tire after a ride on a hot day when the tire air temperature is 65◦c? (assume constant volume and a constant atmospheric pressure of 101.3 kpa.) answer in units of kpa.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
